I came across this article while in another post. I thought it was quite interesting. We often have debates about red shirting, those for and those against. This artivle is quite interesting. It links more than one article to support these claims, so I'll post the link if anyone wants to follow it to those articles.
I think it's interesting. Also the first comment to this article brings up a good point, is kindergarten getting too competitve? Or on the flip side of that, have we just begun to realize that we need kindergarten to stay current in ordert o compete in the world.
Here’s a good explanation of how this accumulated advantage works in sports. For example, see this article , which
reveals how elite Canadian youth hockey teams are more likely to have
players born early in the calendar year, a phenomenon also found among
professional hockey players.
This “accumulated advantage” over time was named the Matthew effect by sociologist Robert Merton, from the Biblical quotation in Matthew: “For to all those who have, more will be given, and they will have an abundance; but from those who have nothing, even what they have will be taken away.” The Matthew effect has also been shown in soccer, swimming, tennis, and major league baseball .
“From his analysis, Elder found that the youngest kindergarten kids were 60 per cent more likely to be diagnosed with ADHD than the oldest in the same grade, and also, by the time those groups reached the fifth and eighth grades, the youngest were more than twice as likely to be on prescription stimulants. Elder estimated that overall in the US, the misdiagnosis rate is about 1 in 5, that is around 900,000 of the 4.5 million children currently diagnosed with ADHD have been misdiagnosed.”
